l'ii'ting jacks or siinilar battery handling apparatus are expensiveand, While the purchase of such apparatus is not a serious inqconvenience where a nuinber ol" trucks have to 1oe serviced, it is asubstantially prohilf tive expense and inconvenience to a person owninglint a single electric truck. 'll'iis fact Works a prejudice against thepurchase electric trncli's Where only one or tivo trucks are required.

lt a. principal object olf this invention to incorporate as a part ofthe electrically driven vehicle an apparatus for lil'ting and supportingthe vehicle battery. 'flllie apu paratns inay readily be actuated by oneperson to elevate the battery into position on the vehicle or lowerit tothe l'loor or other suitable support. 'lhe battery hantiling` apparatusis permanently assembled on the vehicle and is at all tiines ready forinnnediate use in raising1 or loweringv tlc battery.

is an obj et oi" the invention to provide on the vehicle a batteryhandling` apparatus ol this nature which is oli sach low cost that itinay be installed on each vehicle at an inconsiderable increase ininanulactr-.ringl cost over that iiorn'ially required lor the veli'cle.in this ifa bien the necessity olf an expensive lifting jacli orequivalent battery liai'idlnip` device is eliminated, and the individualowner oi' one or two truclis is not pnt to the necessitY of investing ina special b ttery handling unit for the purpose ol attendin@I to hisstorage batteries.

The invention tlieieliore conten'iplates the provision ol anelectrically driven vehicle as a part ol' its regular equipment suitableineclianiisni to enga. i and. support the veu hic-le battery and sin leactuating inecliathrough .vhielV an applied .torce ot iitude, sach forinstance a inanual snort, will serie to litt the battery or lower ittroni the vehicle as desired. lfhe invention does not resi e ln'oadly ina relates specilically to novel inecl anisin, but

n electrically driven vethe provision o'f hielo havingl permanentlyasseinbled upon it a battery liandfii device ol the character described.'lhc ose ol' the invention is to avoid in eonnnercial practice thenecessity ol a separate expensive battery liandlinn` unit.

l have illustrated a preferred embodiment of my invention in theaccompanying drawings in which Figure 1 is a. view taken transversely ora vehicle embodying my invention; Figure 2 is a plan view ot' theapparatus shown in Figure 1; Figure 3 is a view taken on line 3 3 otFigure Figure t and 5 are views similar to Figures l and 2 respectivelyillustrating a somewhat different toi-in of apparatus; Figures 6 and 7are views similar respectively to Figures 1 and 2 showing a furthermodification.

' Referring to the drawings, 1 indicates the traine or chassis ot thevehicle and 2 indicates the battery cradle or support which serves tocontain the storage battery provided for supplying the driving powerYtor the vehicle. The construction ot the battery cradle and the mannerof attachment of the battery to the vehicle here shown correspond to thedisclosure of the copending application orn iValter S. lVard andBenjamin H. Britt, Serial No. 647,997 filed lune 2'?, 1929.

Vilith this arrangement a pair of transversely extending angle irons 3are secured to the trame members 1 of the vehicle, and depending fromthe transverse members 3 are supporting` bars or straps Il, eachprovided with loops at its lower end as indicated at The battery cradle2 is provided with cooperating supporting straps 6 eachv having a loop 7at its upper end arranged to be brought into alignment with the loops 5,as indicated in Figure 1, so that a supporting` bar 8 may be threadedthrough the respective loops at opposite sides ot the battery cradle 2to thereby constitute a support tor the battery. lt Will be understoodthat While the battery handling apparatus of the present invention isparticularly designed ter use in connection With a battery support otthe type shown herein, it is nevertheless equally applicable to theraising and lowering otl batteries irrespective of the particular ashionin which the battery is secured to the vehicle tor transportation.

rilhe invention contemplates means for enthe battery and suitablemechanism for raising or lowering of the battery as desired. Fo this enda chain or other appropriate means ot support is arranged to engage withthe battery and is also arranged to engage with appropriatemechanism-provided oii the vehicle frame to eliiect actuation of thechain to thus move the battery. The actuating mechanism consistspreferably oi a system of reduction gearing such that vertical movementot the battery may be accomplished by the exertion ot a relatively smallmanual effort, as 'tor instance by the turning oi a hand crank.

.in the embodiment ot Figures 1 to 3 a shaft 9 entends between thetransverse supporting members 3 and is tree to rotate in its bearings 10supported on the members 3.

Shaft 9 carries atV about the middle of its leng 1 a ivorm Wheel 11actuated by a Worin 12 provided on a shalt 13 extending transversely otthe vehicle and being supported in any desired fashion as for instanceby members 1l extending betiveen the transverse supporting members 3.Shaft 13 extends to one side of the vehicle and, as indicated at 15,isprovided for attachment to a crank handle 1G which may be manuallyturned to accomplish elevating of the battery.v

ist respective ends the shaft 9 is -provided ivith sprocket Wheels 1'4"which operate chains 13. Une end ot each ot the chains i3 is secured 19to the vehicle trame While thel other end is attached at 20 to thebattery. Upon manual actuation ot the crank 1G, therefore, shaft 9 willbe rotated through the medium of the Worin gearing 11 anc l2 With heresult that sprockets 17 will serve to nieve the chains 13 and therebyelevate or lovver battery cradle 2 depending upon the direction otrotation ot the crank 16. The ratio ot reduction is such that areasonable manual effort exerted upon the crank 1G will serve to producethe requisite movement ot the battery. `We have found that for theprovision ot effective inexpensive battery handl' device ot this nature,it is not ordinaiily necessary or advisable to resort to power drivenmeans for elevating or low -i the battery.

rllie embodiment of Figures l and 5 utilizes a sprocket 21 at each sideof the battery cradle 2. Vilith this arrang ment the res tive ends ofthe chain are preferably secured to the vehicle trame as indicated at 22ant 23. .Sie loopl or the chain extends d'ovsn. around sprocket 21 andfrom thence up and lv around driving sprochet 1'?. rfhis has theadvantage. of atording an additional 2 to 1 mechanical advantage for thereason that the extent ot movement of the battery is only one halt thatoi the chain passing over the periphery of sprocket. 17. lilith thisarrangement a lesser reduction inthe gearing is required. i

Figures 6 and 7 disclose an embodiment wherein a four point suspensionot the battery is 1obtained rather than a tn'o point suspension. frchain 1S is provided at each side oi the battery cradle. rThe respectiveends or the chain are secured tc the battery cradle by means of hooks orthe like as indicated at 2st- 'lvvo driving shafts 9 are provided andeach chain 13 is trained Vover the driving sprockets ot each of theshafts 9 and a suit` able amountof slack in the chain etiveen the twosprockets is provided in order to l permit ot an adequate extent ofmovement of the battery. The driving shatt- 13 carries two Worms 12, oneot which is provifled with lett hand threads and the other ot which isprovided VWith right hand' threads. This is It iiS lll? necessary inorder to rotate the respective driving shafts Sl oppositely so that Withthe arrangeinent of the chain as shoivn each sprocket will serve to lifUthe battery upon rotation of the crank lo in one direction and to loivcr`lie battery upon rotation of the cranlr in the other direction.
